REGULATOR FOR USE WITH FILLING-VALVES.

Specification of Letters Patent.

To all whom it may concern.-

Be it known that I, ADOLPH SCHNEIDER, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illincis, haveinvented certain new and useful Improvements in Regulators for Use withFilling-Valves, of which the following is a specification.

This invention is intended and adapted to be used with valves of thegeneral character described in Letters Patent No. 728,307 and otherpatents to the same inventor, in which the valve is provided with liquidand air equalization passages, so that the pressure in the bottle andthe tank will be equalized before the liquid begins to flow. In valvesof the character indicated it sometimes happens that the liquid-passageswill be slightly opened before complete equalization takes place, inwhich case the liquid will be sucked into the bottle by reason of thegreater pres sure in the tank, which causes foaming and prevents thebottle from being completely and perfectly filled.

The object of the present invention is to overcome this di'l'liculty byproviding a regulator which will prevent the discharge of any liquidwhatever into the bottle before equali zation and is intended entirelyas an attachment to the valve and not as a substitute therefor, so thatwhen the valve is operated perfectly the regulatorwill remain inactive,but will serve as a safeguard to insure the proper operation of thevalve at all times.

The invention consists in the features of construction and combinationof parts hereinafter described and claimed.

In the drawings, Figure l is a sectional view of a valve of thecharacter indicated, showing the regulator in place Fig. 2, a sideelevation of the valve, showing a slightlymodified form of regulator insection; Fig. 3, a cross-sectional view of the regulator of Figs. 1 and2, and Figs. 4 and 5 views showing slightlynnodilied forms of regulator.

The regulator which more especially forms the subjectmatter of thepresent invention consists of an inverted-Ushaped tubular casing 1,having at its attaching end screwthreads 2 or other suitable attachingmeans and having in its body a continuous passage 3, terminating at itsouter end in an enlarged chamber 4, leaving a tapered shoulder 5, whichserves as a valve-seat. The enlarged l l l l her is a movable valvemember 7, adapted to move up and down within the enlarged chamber andprovided with ribs or flanges 8, which contact the walls of the chamber,leaving spaces 9 for the passage of liquid up around the valve member.The valve mem ber is tapered at its inner end 10 and adapted to seatagainst "he beveled shoulder 5 when in raised position and when unseatedrests upon a cross-pin 11, as shown in Fig. 1. In Fig. 2 the movablemember 12 is constructed of a su'llicient length to project out of thechamber and rest when unseated upon the walls 6 of the tank, thecross-pin being dispensed with. In Fig. 4 is shown a slightlymodiiiedform of construction, in which a tubular casing 13 is emp oyed providedwith attaching screw-threads 1d and having a passage 15, terminating ina chamber 16, similar to that hitherto described, and above the chamber16 is a bore 17, leaving a shoulder 18 for the contact of a coiledspring 19, which is adapted to bear down against a valve member 20. Thevalve member in this instance is provided with an upwardly-projectingstud 21, around which the spring is coiled, and normally rests upon across-pin 22, being held thereon by the tension of the spring. It willbe understood that in the construction of Fig. 4 the spring serves toexert an additional tension upon the valve member, so that it wilrequire a greater amount of pressure to seat the member against thebeveled shoulder. In Fig. 5 the valve member 7 a is ball-shaped but thecasing is similar to that of Fig. 1.

The regulator is screw-threaded or otherwise secured to a neck 23, whichforms part of a valve-Casing 24, and within the valvecasing is a beveledvalve-plu 25, held in place by means of caps 26 at the ends of avalve-casing. The casing is provided with a liquid-supply passage 27,connecting with liquid-passage 28 in the valve-plug, and said passageleads to and communicates with the filling-tube 29, which passes througha fillinghead 30, having a neck 31 screwthreaded into the valve-plug.Within the liquid-supply pipe is an air-p assage 32, opening at itsupper end into an annular chamber 33, which communicates by means ofairpassages 34 and 35 with an air-pipe 36,the valve being in allessential features the same as that described in the prior patentreferred to, and the passages 34 and 35 are preferably arranged so thatsaid passages will come into communication with one another prior to thealineinent of the liquid-supply passages, thereby enabling aprelin'iini'iry equalization of pressure. It will be understood,however, that the invention is not limited to use with valves of theprecise character herein described, since it is adapted for use with anypressure-equalization valve.

In use the valve member in the regulator will normally remain seated, sothat when the liquid llows down by gravity after the pressure has beenequalized the regulator will remain in normal position. if, howe er, thepressure should be imp erieei'ily equalized in the bottle prior to theadmission oi" liquid, said liquid will begin to rush through theregulator, and said unusual rush oi liquid Will serve to force up thevalve member Within the regulator and seat the same, thereby cutting oilthe llowo'i liquid until i he pressure has been properly equalized, atwhich point, there bein no suction from the bottle and no abnormal l lowof liquid through the regulator, the valve member therein will drop tonormal position, allowing the liquid to flow unimpeded through theregulator and valve into the bottle. ll the action of the regulator ofeither Figs. 1, 2, and 5 be too free and the valve member too easilyseated, the regulator of if 4 may be substituted, which is provided witha coil-spring, \\"l\l(l1 prevents the easy seating oi the valve. Inother respects the operation of the two is entirely the same.

It will be seen. from the foregoing description that the regulator ofthe present invention can be easily and quickly attached to Valves ofthe character indicated and when. so attached will serve to regulate andcontrol the operation of said valves and prevent the possibility ofimperfect action. Another feature of importance lies in the fact thatthe regulator serves to prevent any sudden inrush of liquid, which, itviolent, sometimes breaks the bottle, thereby resulting in injury to theattendant and waste of the liquid.

What I claim as new, and desire to secure by Letters Patent, is

1. In combination with a pressureequalization valve, a regulator havingan imperferate valve member normally unseated and adapted to be seatedby an abnormal rush of liquid tl'irough the valve to tightly seal theopening, substantial y as described.

2. In GOJHbiHFtUiUlI with a pressureequalization valve, a regulatorconsisting of a tubular casing, and a movable imperforate valve memberin one end of the casing adapted to be seated by an abnormal rush oiliquid through the regulator and equalization-valve to tightly seal theopciiing, substantially as described.

3. in combination witha pwssure-equalization valve, a regulator having atubular casing of inverted-U shape having one end inserted into theliquid-passag oi the equalization-valve and the other end. downwardlyopening and formed. with an enlarged chamber providing a seat, a movableimperiorate valve member normally open and adapted to be seated by an.abnormal rush of pressure through the regulator and equalization-valveto 'gitly seal the opening, substantially as described.

4. in combination with a pressure-equalization valve, a regulatorconsisting oi a tubular casing of inverted-U shape having one endinserted into the liquid-supply passage of the equalizathan-valve andthe other end opening downwardly and provided with an enlargedvalve-chamber beveled at its inner end to form a art, and, animperiorate valve member slidably mounted within the chamber andprovided With-ribs or flanges around its outer wall and adapted to beseated by an abnormal rush of liquid through the regulator andequalization-wrlve to tightly seal the o iening, substantially asdescribed.

5. In combination with a pressureequalization valve a regulator having atubular casing of inverted-U shape having one end inserted into theliquid-passage oi the equalization-valve and the other end downwardlyopening and 'l'ormed with an enlarged chamber providing a seat, amovable imperforate valve member i'iormally open and adapted to beseated by an abnormal rush of pressure through the regulator andequalizationvalve to tightly seal the opening, and a spring for normallyholding the valve unseated, substantially as described.
